SHUTTER-FASTEN ER.

SPECIFICATION forming part of Letters Patent No. 415,437, dated November 19, 1889.

Application filed March 20, 1889. Serial No. 303,951. (No model.)

To aZZ whom it may concern:

Be it known that we, GEORGE BENSEL and OTTO THEODORE MAIER, both of New Orleans, n the parish of Orleans and State of Louislana, have invented a new and Improved Fastening for Doors and Shutters, of which the following is a full, clear, and exact description.

The object of the invention is to provide a new and improved fastening for doors and shutters which permits of opening the doors or shutters from the outside in case of fire.

The intention consists of a pin or pins supporting the lock and projecting to the outside of the door or shutter, and provided with an annular groove near the outer end, and a collar held on the outer end of the pin and terminating at the said groove.

The invention also consists of certain parts and details and combinations of the same, as will be fully described hereinafter, and then pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 is an outer face View of a pair of shutters provided with our improvement. Fig. 2 is a transverse section of the same on the line a: 00 of Fig. 1. Fig. 3 is a sectional plan View of the improvement on the line y y of Figs 2. Fig. l is an enlarged sectional elevation of the collar. Fig. 5 is a side elevation of the pin, and Fig. 6 is a transverse section of the improvement as applied to another form of lock.

The improved device A is provided with one or more pins B, passing transversely through the shutter or door 0, which when closed holds the other door or shutter C in place in the usual manner. The inner end of the pin B is adapted to support the lock D, which may be of any approved construction, and according to the latter the shape of the inner end of the pin B is varied to suit the lock.

As illustrated in Figs. 1, 2, and 3, the lock D comprises a wedge E, passed through a vertical slot F, formed in the enlarged extension F, secured on the innerend of the pin B. The

wedge E presses with one edge against the usual cross-piece G, secured to the casi ng supporting the shutter or door.

As illustrated in Fig. 6, the lock D comprises a cleat I'I, secured to the shutter or door O by two pins B. On the cleat II is pivoted a hook I, adapted to engage with its hook end I the cross-piece Gbefore mentioned.

hen the wedge E or the hook I are in place, as shown, the shutters or doors are locked. On the pin B is formed an annular groove J, preferably located in line with the outer surface of the shutter or door C, as is plainly shown in the drawings. On the outer end B of the pin B is held a collar K, terminating at its inner end at the annular groove J and held in place on the pin B by forming a rivet B on the outer end of the pin after the collar is in place.

The inner end K of the collar K is beveled at its lower edge. (See Fig. 4.) When the collar K is in place on the pin B, the latter is securely held on the shutter or door 0 and the latter is opened or closed and locked in place in the usual manner by the lock D, supported by the pin or pins B.

\Vhen the shutters or doors are looked, as above described, and a fire breaks out in the building, and a fireman desires to open the shutter or door from the outside he strikes with ahammer, axe, or other instrument a hard blow on the collar K, so that the end B of the pin B breaks off at the annular groove J, which is the weakest spot on the pin. By then pulling outward on the shutter or door the latter swings outward into an open position, leaving the rest of the pin or pins B and the look I) hung on the cross-piece G. In case two pins are used on one lock D, as shown in Fig. 6, the fireman has to break both pins, as above described.

It will be seen that the device securely supports the shutter or door lock, and at the same time permits a quick opening of the shutter or door from the outside when the same is closed. It will further be seen that the bevel K on the collar K permits the latter to act as a lever when struck by the instrumentin the hands of the fireman, so that one blow sufiices to break off the pin. end B.

Having thus fully described our invention, We claim as new and desire to secure by Letters Paten t 1. In a shutter or door fastening, a pin passing through the shutter or door and supporting the lock on the inside of the shutter on door and projecting on the outside of the shutter or door, the said pin being provided With an annular groove at. or near the outer surface of the shutter or door, substantially as shown and described.

2. A shutter or door fastening comprising a pin passing through the shutter or door and supporting thelock on theinside 0f the shutter or door, and projecting on the out-side of I the shutter or door, the said pin being pro- Vided With an annular groove near the outer end, and a collar held on the outer end of the said pin and terminating at the said annular groove, substantially as shown and described.

3. In a door or shutter fastening, the fastening-pin B, having a weakened portion be tween its ends, and a collar 011 its outer end terminating at said Weak part, substantially as set forth.

4. The combination, with a shutter or door, of a pin held loosely in the said shutter or door and provided with an annular groove, a lock supported on the said pin on the inside of the said shutter or door, and a collar held on the outer end of the said pin at the outside of the shutter or door, the said collar terminating at the said annular grcove and beveled at K, substantially as shown and described.
